When our forefathers first sailed to this country and started working American soil for food, they had no idea that their methods were actually hurting the productivity of the soil. After all, the vast prairies of this continent had millions of years to build up proper carbon, nitrogen and potassium levels. If tilling the soil was actually draining those nutrients and hurting its productivity, it certainly wasn’t apparent to early settlers.

Despite concerns about global warming, no-tillers have already helped American agriculture turn the corner. It’s good news not only for farmers, but environmentalists as well.

For several years, there's been talk in western Canada about offering tax credits to no-till farmers who store additional carbon in the soil. A few years back, Canadian utility companies saw the concept as a way to offset huge penalties for atmospheric emissions from coal-powered electric plants.
